Caroline Flack has some very clear – and honest – advice for viewers of Love Island who may be prudish about young, sexy singletons sleeping together on TV.

“If you don’t want to watch rumpy-pumpy, turn it off!” she laughs. “We only ever show naughty bits if it’s relevant to the storyline, and part of the story is that they might get it on at the end of the night. That’s what happens in relationships.”

Last year’s series of the reality show – where 12 strangers must ‘couple up’ over the course of seven weeks in a Majorcan villa – caused controversy for airing intimate moments between the contestants, and it seems producers are actively encouraging more of the same this year, with a brand-new residence.

“It’s sexier and has lots more hideaways,” explains Caroline. “The boys are all really hot, and the girls are ridiculously hot! If you’re looking for a raunchy, racy, emotional way to spend your summer, then this is the perfect show for you.”

In fact, there’s so much scandal that, for the first time, ITV2 will also be airing a live weekly spin-off show, Aftersun, on Sunday nights.

“We’re going to have a good old gossip,” says Caroline. “We’ll have celeb guests, former contestants and fans. We’ll also have relationship experts, who are going to tell us who loves who.”

With viewing figures last year up by around a million per episode on 2015’s series, what’s the secret to the show’s success?

“We all like to pretend we’re relationship experts. We all give advice to our friends.

“Probably 70 per cent of all my conversations with my girlfriends are about their relationships or someone else’s. It’s real, it’s about real people and we get invested in it. These people are putting their hearts on the line…”

As before, Caroline will be dropping into the villa unannounced with shock updates and surprise twists, which has always caused a stir among the islanders.

“I think they’re half-excited, half-nervous when they see me because it usually means somebody is for the chop!” she laughs.

Asked to pick out her favourite ex-contestants, Caroline doesn’t hesitate.

“The first year I loved Jess Hayes,” she says.

“She ruffled feathers, but she was the one who kept getting her heart broken, which is so relatable. Everyone wanted Jess to find love.”

Caroline also admits she has a soft spot for last year’s winners, TOWIE stars Cara de la Hoyde and Nathan Massey, who are currently expecting a baby but are no longer together.

“We’re creating lives on Love Island!” she enthuses. “It’s so cute, I love it. Cara and Nathan were together from the very start of the series – and that was such a rarity.”

Despite the abundance of hunks in tiny trunks, Caroline has never been tempted to snag one for herself. Assuming she is single, that is…?

“I’m not going to talk about my dating!” she insists. “I’m like an older sister on the show. I feel protective – being protective and fancying someone don’t come at the same time. But I would have jumped at the chance to be on the show when I was between 18 and 21. Love Island reminds me of being on holiday when I was young.”

After a doomed stint presenting The X Factor alongside Olly Murs in 2015, it appears that Caroline has landed on her feet hosting a show that requires her to bask in the Spanish sunshine. She insists, though, it isn’t one long holiday.

“It isn’t like that,” Caroline laughs. “I fly in and out, but when I’m there I stay in a hotel with everyone on the production team, which is fantastic. It’s one of the best jobs in telly.”
